Curious about the "R-15"?
I see R-11 and R-13 batts,
who makes the R-15?

owens corning, r15 for 2by4 walls, most yards around new york carry it.

R-15 bats?

I'm curious as well...

(I'm certainly not the grammar sheriff, but your post is a run-on mess...can you be a bit clearer?)

What kind of windows are you using? Anything other than 1/2" inside (sheetrock) and 1/2" outside (sheathing), means you will likely need extension jambs when you go to trim the inside with casing, sill & apron.


EDIT: Just found the R-15 on the OC site--I'm in the same area as Neolithic & can't say I've seen that offered in our area.

Did they actually allow you to put a real Dryvit EFIS system over wood frame? - or is it just a sythetic stucco system?
